Abstract

A process for obtaining a ceric oxide. More precisely, a process for increasing and stabilising the specific surface of a ceric oxide at high temperature. <??>The process of the invention, which consists in preparing a ceric oxide by calcining a ceric hydroxide, is characterised in that the ceric hydroxide is subjected to a solvothermal treatment before the calcination operation.
